SUMMARY:Speaker: Andrei Cuceu (LBNL) - Title: DESI DR2 results: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESCRIPTION:Research Progress Meeting \nDate: March 19\, 2025 \nTime: 3:00- 4:00 pm \nLocation: B50 Auditorium [In-Person and HYBRID]  \nSpeaker: Andrei Cuceu (LBNL) \nTitle: DESI DR2 results: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints \nAbstract: The Dark Energy Spectroscopic Instrument (DESI) is conducting a 5-year redshift survey of 40 million extra-galactic sources over 14\,000 square degrees of the northern sky. One of its primary goals is to measure the cosmic expansion history across a wide range of redshifts using baryon acoustic oscillations (BAO). The first DESI results\, released in 2024\, were based on the first year of data and showed intriguing hints that dark energy may not be described by a cosmological constant. On March 19th we will announce a new set of BAO measurements which are based on the first three years of DESI data. We will also present the cosmological implications of these measurements alone and in combination with cosmic microwave background\, supernovae\, and weak lensing experiments. These include constraints on the expansion rate of the Universe\, the nature of dark energy\, and the sum of the neutrino masses. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91957913705?pwd=VS307QTLzyDvXZuaZd7WxyBNKVl5UD.1 \nMeeting ID: 919 5791 3705\nPasscode: 288371
